In my lecture today I watched a video on plant reproduction. It showed how some plants rely on specific animals for reproduction. It primarily focused on species of lilies and orchids. The way these plants trick insects in order to reproduce is amazing. The video was called Sexual Encounter with the Floral Kind.

That is awesome. I can't believe that is really the title, though! That is so funny. Was it about how their flowers looked like the females of a certian speices of wasp, and stuff like that?

Did you know some flowers smell good and some flowers smell like raw meat, because the nice smelling ones are polinated by bees and they are attracted to the sweet smell whiles the other ones are polinated by flies which are attracted to... not so nice smells.

Actually yeah that was what the movie was exactly about. It's amazing to see how plants can purposely be so tricky towards insects. I have new respect for them.

I have a nice plant in my little front yard. The female flower is red, the male flower is yellow. I do not know what the name of this plant I will try to take a pic of it and upload it here then I like to give you a HW

If seeds that have fallen on the ground are covered with a little dirt, another plant may start to grow. Seeds can be planted by people, too.

Plants can be started from a cutting - either a stem or a leaf put in sand or water.

Layering - a branch laying on the ground covered with a little dirt might grow roots and start another plant.

Runners - stems grow underground to produce new plants.

Spring is a wonderful time of a year. Flowers are everywhere. Blooming trees, bushes, and plants are beautiful. The air is filled with their sweet fragrances. Bees and butterflies are flying from one bright flower to another. Why do they do that?

2 You know, of course, that bees produce honey. They make it from nectar they gather from flowers. Nectar is a sweet and viscous liquid. It is located in plants' blossoms, leaves, and stems. Different living things use nectar as their food--bees, wasps, butterflies, moths, even some birds and mammals! But they are not the only ones who benefit from it. Nectar-eating insects and birds also help flowering plants reproduce.

3 You may have observed tiny yellow grains inside some flowers. This is called pollen and it is used by flowers to form seeds. Plants make the pollen in the saclike anthers of their flowers. The anthers are part of the stamen--the male part of reproduction. The female part is called the pistil, and it includes the stigma and the ovary. The stigma receives the pollen and leads it to the ovary--the egg-bearing part of the plant. The process of moving pollen from anthers to stigma is called pollination.

4 When pollen reaches the egg cell inside the ovary, it causes the cell to divide. Each cell then becomes a seed embryo and develops into the seed. This process is called fertilization. Because of fertilization, seeds have characteristics of both male and female cells. Some plants have both pistils and stamens on their flowers. They are perfect flowers. They can transfer pollen from their own anthers to their own stigmas. This process is called self-pollination.

5 It is necessary for self-pollinating flowers to prevent other plants' pollen from getting into their stigmas. This is why in some flowers the pollination occurs before the blossom opens. Some other flowers are so constructed that pollen from other blossoms simply can't enter them. Look at the flowers of beans, peas, or snapdragons. They grow a kind of a trap door for protection against other pollens. You may also notice that these flowers have no scent. Can you tell why?

6 But not all flowers are perfect. Some of them have only pistils and are considered female flowers. Others have only stamens, which makes them male flowers. These kinds of flowers are called cross-pollinating. They must depend on wind, insects, birds, or other means to carry their pollen from male flowers to female ones. This is why they have showy blossoms, a fragrant scent, and sweet nectar, all of which attract various insects and birds. They fly from flower to flower and transport sticky pollen on their feet and bodies.

reproduction is the biological process by which new individual organisms are produced. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction by an antecedent. The known methods of reproduction are broadly grouped into two main types: sexual and asexual reproduction.

In asexual reproduction, an individual can reproduce without involvement with another individual of that species. The division of a bacterial cell into two daughter cells is an example of asexual reproduction. Asexual reproduction is not, however, limited to single-celled organisms. Most plants have the ability to reproduce asexually.

Sexual reproduction requires the involvement of two individuals, typically one of each sex. Normal human reproduction is a common example of sexual reproduction. In general, more-complex organisms reproduce sexually while simpler, usually unicellular, organisms reproduce asexually.
